JOSEPH HENRY BURDOCK, OF ALBIA, IOWA.

LIGHT-EXTINGUISHER.

T 0 all whom it may concern:

Be it known that I, JOSEPH HENRY BUR- DOCK, a citizen of the UnitedStates, and a resident of Albia, county of Monroe, and State of Iowa,have invented certain new and useful Improvements inLight-Extinguishers, of which the following is a full, clear, and exactdescription.

This invention relates more particularly to a device forextinguishingvthe lights in stores at agiven time.

The primary object of the invention is to provide simple and efficientmeans whereby the gas or other lights of a store or other building maybe automatically extinguished at a given time, thus saving in theconsumption of the gas or other lighting means without requiring theattendance of any person as is the usual case where it is desired thatone or more lights burn at night in a store or other location, and whichshould be extinguished as soon as it is claylight.

A further object of the invention is to provide a simple device whichmay be easily constructed and arranged convenient to the source of lightsupply, and which is adapted to automatically control the lightingmeans.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a perspective View of one form of deviceembodying my invention. Fig. 2 is a vertical section, partly inelevation, showing one application of the device; and Fig. 3 is a planView, partly in section, of the device.

The casing 10 may be of any suitable material and of any desired sizeand form. As shown it is substantially rectangular, and is provided witha door 11 which may be locked to prevent access thereto except through aproper key, and at one side of the casing is a clock 12. This clock 12may be of the usual alarm type which may be set to release a shaft 13instead of ringing the alarm at any desired time, though instead of aclock any suitable mechanism may be employed.

The shaft 13 is provided with a spool or drum 14, and held to the drumis a cord or other flexible connection 15 which is adapt- Specificationof Letters Patent.

ed to pass around a sheave or pulley 16 suitably held in a bracket 17extending downward from the top 18 of the casing. One end of theflexible connection 15 is fastened to a drum 19, and this drum 19comprises two parts 20 and 21, one of which, as 20, may beularger thanthe other, and to said part 20 one end of the flexible connection 15 issecured. The drum is provided with a shaft 22, and this shaft has ahearing at one end in a bracket 23 and the bearing for the other end ofthe drum is formed by the top 18 in which is an opening 21 of the sizeof the part 21 of the drum 19 so that the latter will properly rotatetherein, and to the part 21 of the drum is secured one end of a flexibleconnection or cord 25 which passes around a sheave or pulley 26journaled in a bracket 26 and to the opposite end of the flexibleconnection 25 is fastened a weight 27. As will be seen when the time atwhich the clock is set to release the shaft 13 arrives, the said shaftwill rotate and by reason of the weight 27 and the drum 19 will berotated in its bearings, the said drum being normally held againstrotation and against the action of the weight 27 by reason of the clockmechanism which holds the shaft 13 from rotating.

As a means for causing the drum to automatically extinguish the light orlights, I provide the drum 19 with a slot or recess 28 which is adaptedto receive the handle 29 of the usual gas cook 30 which is adapted tocontrol one or more burners 31. When the lights are burning, the drum isheld against rotation by the action of the weight 27, or a spring ifsuch is used, by means of the clock mechanism and the shaft 13, but assoon as the shaft 13 is released, the weight 27 will rotate the drum andwill impart a movement to the handle 29 of the gas cook 30 and shut offthe gas supply at the time the mechanism of the clock is set. 1

The part 20 of the drum 19 may be provided with a plurality of openings32 which are spaced apart around the periphery thereof, and are adaptedto receive a plug in the end of the cord 15 so as to position the drumto permit the handle 29 of the cook 30, or other regulating means, tocause the light or lights to be adjusted to any desired degree accordingto the opening in which the plug in the cord 15 is inserted.

While I have shown the invention as applied to extinguishing a lightcaused from a single burner, it will be understood that the controllingmeans may be set to govern a number of lights, and that instead ofcontrolling the gas supply, the device may be made to control electriclights by having the same operate a suitable switch instead of a gascock or valve.

From the foregoing it will be seen that a simple device is providedwhereby lights may be automatically extinguished at any desired timewithout the presence of any attendant, thus economizing in the use ofthe light-supplying medium; that said device is easily constructed andmay be readily applied in various ways and means, and that said deviceis so made that it may be readily removed and the lights controlled inthe usual way.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a device of the character described, thecombination with a casing, of a two-part drum journaled therein andhaving one face provided with means for engaging a controlling device, aflexible connection secured at one end to a part of the drum, a weightsecured to the other end of said flexible connection, a second flexibleconnection connected at one end to the other part of the drum, a shaft,means carried by the shaft to which the other end of the flexibleconnection is held, and time mechanism for releasing the shaft.

2. In a device of the character described, the combination with acasing, of a drum journaled therein and having one face provided withmeans for engaging a controlling device, a weight for operating the drumin one direction, a flexible connection connected at one end to thedrum, a shaft, means carried by the shaft to which the other end of theflexible connection is held, and time mechanism for releasing the shaft.

3. In a device of the character described, the combination with a gascock, of a casing, of a two part drum journaled therein and having aslot in which a part of the cock is adapted to fit, a flexibleconnection secured at one end to a part of the drum, a weight secured tothe other end of said flexible connection, a second flexible connectionconnected at one end to the other part of the drum, a shaft, a spoolcarried by the shaft to which the other end of the flexible connectionis held, and clock mechanism for releasing the shaft at a predeterminedtime to close the cock and extinguish the light.

4. In a device of the character described, the combination with acasing, of a two-part drum journaled therein and having one faceprovided with means for engaging a controlling device, a flexibleconnection secured at one end to one part of the drum, a weight securedto the other end of said flexible connection, a shaft, a second flexibleconnection secured at one end to said shaft and at the other end to theother part of said drum, and means for releasing the shaft at apredetermined time.

This specification signed and witnessed this third day of August A. D.1908.
